Abstract

A shoe sole 3 of the present invention comprises a midsole 4 and an outsole 5, in which the outsole 5 includes a cushion member 10 formed beneath the midsole 4, in a shape of a series of zigzags, with a determined thickness and width. The cushion member may disperse the wearer'"'"'s weight uniformly to the whole area of the shoe sole and may provide comfortable deformation of the shoe sole according to the wearer'"'"'s walking behavior due to spaces defined in the cushion member. Since the cushion member gets opened and shrunk repeatedly while walking, the wearer can propel one'"'"'s round walking, thereby that the shoe sole can reduce the fatigue of the wearer'"'"'s feet and protect the wearer'"'"'s joints like ankles and knees safely.

Claims

1. A shoe sole with propelling function for impact dispersion and round walking, the shoe sole comprising a midsole 4 and an outsole 5,

wherein the outsole 5 includes a cushion member 10 formed beneath the midsole 4, in a shape of a series of zigzags, with a determined thickness and width.

2. The shoe sole of claim 1, wherein the cushion member 10 provides a space 11 defined inside a zigzag curved section to have one lateral opening, thereby to disperse impact.

3. The shoe sole of claim 2, wherein the zigzag curved sections at both lateral sides in the outsole 5 are relatively thicker and wider than middle section.

4. The shoe sole of claim 2, wherein the opening of the space 11 is narrower than inside of the space 11.

5. The shoe sole of claim 1, wherein the thickness of the cushion member 10 increases gradually from a medial arch to a heel, and

the thickness of the cushion member 10 increases and then decreases gradually from the medial arch to a toe.

6. The shoe sole of claim 1, wherein a toe and heel portions of the cushion member 10 are formed wider than a middle portion thereof.

7. The shoe sole of claim 1, wherein the zigzag shaped cushion member 10 is provided independently with a support member 20 which is formed on the cushion member 10 in a shape of a sole of the foot.

8. The shoe sole of claim 7, wherein the midsole 4 is provided on the cushion member 10.

9. The shoe sole of claim 1, further comprising a non-slip pad 6 attached on the whole or part of bottom of the cushion member 10.

10. The shoe sole of claim 1, wherein the cushion member 10 is shaped in a series of zigzags from the heel portion to the toe portion.
